Recommended Land Pattern
In case of flow soldering, the land width must be smaller than the Chip Resistor width to control the solder amount prop-
erly. Generally, the land width should be 0.7 to 0.8 times (W) of the width of chip resistor. In case of reflow soldering, solder
amount can be adjusted, therefore the land width should be set to 1.0 to 1.3 times chip resistor width (W).

Recommended Soldering Conditions
Recommendations and precautions are described below.
●
Recommended soldering conditions for reflow
· Reflow soldering shall be performed a maximum of
two times.
· Please contact us for additional information when
used in conditions other than those specified.
· Please measure the temperature of the terminals
and study every kind of solder and printed circuit
board for solderability before actual use.

Safety Precautions
The following are precautions for individual products. Please also refer to the precautions common to Fixed Resistors
shown on page ER3 of this catalog.
1. Take measures against mechanical stress during and after mounting of Anti-Sulfurated Thick Film Chip Resistors
(hereafter called the resistors) so as not to damage their electrodes and protective coatings.
2. If a transient load (heavy load in a short time) like a pulse is expected to be applied, check and evaluate the operations
of the resistors when installed in your products before use.
Never exceed the rated power. Otherwise, the performance and/or reliability of the resistors may be impaired.
3. Do not use halogen-based or other high-activity flux. Otherwise, the residue may impair the resistors' performance
and/or reliability.
4. When soldering with a soldering iron, never touch the resistors' bodies with the tip of the soldering iron. When using a
soldering iron with a high temperature tip, finish soldering as quickly as possible (within three seconds at 350 °C max.).
5. As the amount of applied solder becomes larger, the mechanical stress applied to the resistors increases, causing
problems such as cracks and faulty characteristics. Avoid applying an excessive amount of solder.
6. Do not apply shock to the resistors or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise, the resistors'
protective coatings and bodies may be chipped, affecting their performance.
7. Avoid excessive bending of printed circuit boards in order to protect the resistors from abnormal stress.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.

Safety Precautions
(Common precautions for Fixed Resistors)
• When using our products, no matter what sort of equipment they might be used for, be sure to make a written agreement
on the specifications with us in advance. The design and specifications in this catalog are subject to change without
prior notice.
• Do not use the products beyond the specifications described in this catalog.
• This catalog explains the quality and performance of the products as individual components. Before use, check and
evaluate their operations when installed in your products.
• Install the following systems for a failsafe design to ensure safety if these products are to be used in equipment
where a defect in these products may cause the loss of human life or other significant damage, such as damage to
vehicles (automobile, train, vessel), traffic lights, medical equipment, aerospace equipment, electric heating appliances,
combustion/gas equipment, rotating equipment, and disaster/crime prevention equipment.
½
Systems equipped with a protection circuit and a protection device
½
Systems equipped with a redundant circuit or other system to prevent an unsafe status in the event of a single fault
(1) Precautions for use
• These products are designed and manufactured for general and standard use in general electronic
equipment (e.g. AV equipment, home electric appliances, offi ce equipment, information and communication
equipment)
• These products are not intended for use in the following special conditions. Before using the products, carefully check
the effects on their quality and performance, and determine whether or not they can be used.
1. In liquid, such as water, oil, chemicals, or organic solvent
2. In direct sunlight, outdoors, or in dust
3. In salty air or air with a high concentration of corrosive gas, such as Cl
2
, NH
3
, or NO
2
4. In an environment where strong static electricity or electromagnetic waves exist
5. In an environment where these products cause dew condensation
6. Sealing or coating of these products or a printed circuit board on which these products are mounted, with resin or
other materials
• These products generate Joule heat when energized. Carefully position these products so that their heat will not affect
the other components.
• Carefully position these products so that their temperatures will not exceed the category temperature range due
to the effects of neighboring heat-generating components. Do not mount or place heat-generating components or
inflammables, such as vinyl-coated wires, near these products .
• Note that non-cleaning solder, halogen-based highly active flux, or water-soluble flux may deteriorate the performance
or reliability of the products.
• Carefully select a fl ux cleaning agent for use after soldering. An unsuitable agent may deteriorate the
performance or reliability. In particular, when using water or a water-soluble cleaning agent, be careful not to leave
water residues. Otherwise, the insulation performance may be deteriorated.
(2) Precautions for storage
The performance of these products, including the solderability, is guaranteed for a year from the date of arrival at your
company, provided that they remain packed as they were when delivered and stored at a temperature of 5 °C to 35 °C
and a relative humidity of 45 % to 85 %.
Even within the above guarantee periods, do not store these products in the following conditions. Otherwise, their
electrical performance and/or solderability may be deteriorated, and the packaging materials (e.g. taping materials)
may be deformed or deteriorated, resulting in mounting failures.
1. In salty air or in air with a high concentration of corrosive gas, such as Cl
2
, NH
3
, or NO
2
2. In direct sunlight
<Package markings>
Package markings include the product number, quantity, and country of origin.
In principle, the country of origin should be indicated in English.
