Reference Specification

DHR Series

High Voltage Lead Type Disc Ceramic Capacitors for General Purpose

Product specifications in this catalog are as of Feb. 2018, and are subject to change or

obsolescence without notice.

Please consult the approval sheet before ordering.Please read rating and Cautions first.

CAUTION

1.OPERATING

VOLTAGE

When DC- rated capacitors are to be used in AC or ripple current circuits, be sure to maintain the Vp-p

value of the applied voltage or the Vo-p which contains DC bias within the rated voltage range. When the

voltage is started to apply to the circuit or it is stopped applying, the irregular voltage may be generated

for a transit period because of resonance or switching. Be sure to use a capacitor within rated voltage

containing these irregular voltage.

OPERATING TEMPERATURE AND SELF-GENERATED HEAT

Keep the surface temperature of a capacitor below the upper limit of its rated operating temperature

range. Be sure to take into account the heat generated by the capacitor itself.

When the capacitor is used in a high-frequency current, pulse current or the like, it may have the

self-generated heat due to dielectric-loss. Applied voltage should be the load such as self-generated

heat is within 20

C

on the condition of atmosphere temperature 25

C.

When measuring, use a

thermocouple of small thermal capacity-K of

0.1mm

and be in the condition where capacitor is not affected

by radiant heat of other components and wind of surroundings.

Excessive heat may lead to deterioration of the capacitor’s characteristics and reliability.(Never

attempt to perform measurement with the cooling fan running. Otherwise, accurate measurement

cannot be ensured.)

3. OPERATING AND STORAGE ENVIRONMENT

The insulating coating of capacitors does not form a perfect seal; therefore, do not use or store

capacitors in a corrosive atmosphere, especially where chloride gas, sulfide gas, acid, alkali, salt or the

like are present. And avoid exposure to moisture. The capacitor is designed to be used in the

insulating media, such as epoxy resin, silicone oil, etc.. There must be 3mm or more

insulating media for each direction of the capacitor. In case of cleaning, bonding, or molding

this product, verify that these processes do not affect product quality by testing the

performance of a cleaned, bonded or molded product in the intended equipment. Store the

capacitors where the temperature and relative humidity do not exceed -10 to 40 °C and 15 to 85. Use

capacitors within 6 months after delivered.

4. BONDING, RESIN MOLDING AND COATING, BOARD TO AVOID

In case of bonding, molding or coating this product, verify that these processes do not affect the quality

of capacitor by testing the performance of the bonded, molded or coated product in the intended

equipment.

In case of the amount of applications, dryness / hardening conditions of adhesives and molding resins

containing organic solvents (ethyl acetate, methyl ethyl ketone, toluene, etc.) are unsuitable, the outer

coating resin of a capacitor is damaged by the organic solvents and it may result, worst case, in a short

circuit.

The variation in thickness of adhesive, molding resin or coating may cause a outer coating resin

cracking and/or ceramic element cracking of a capacitor in a temperature cycling.

Resin material to hot conditions (over

C

100) was weaker to intensity. So such with board to avoid

mechanical stress in this state, please handle it with care.

5. VIBRATION AND IMPACT

Do not expose a capacitor or its leads to excessive shock or vibration during use.

6. SOLDERING

When soldering this product to a PCB/PWB, do not exceed the solder heat resistance specification of

the capacitor. Subjecting this product to excessive heating could melt the internal junction solder and

may result in thermal shocks that can crack the ceramic element.

When soldering capacitor with a soldering iron, it should be performed in following conditions.

Temperature of iron-tip : 400

C

max.

Soldering iron wattage : 50W max.

Soldering time

: 3.5s max.

Failure to follow the above cautions may result, worst case, in a short circuit and cause fuming or

partial dispersion when the product is used.

NOTICE

Cleaning

To perform ultrasonic cleaning, observe the following conditions.

Rinse bath capacity : Output of 20 watts per liter or less.

Rinsing time : 5min maximum.

Do not vibrate the PCB/PWB directly.

Excessive ultrasonic cleaning may lead to fatigue destruction of the lead wires.

Capacitance change of capacitor

• Class 1 capacitors

Capacitance might change a little depending on a surrounding temperature or an applied voltage. Please

• Class 2 and 3 capacitors

Class 2 and 3 capacitors like temperature characteristic B, E and F have an aging characteristic, whereby

the capacitor continually decreases its capacitance slightly if the capacitor leaves for a long time..

Moreover, capacitance might change greatly depending on a surrounding temperature or an applied

voltage. So, it is not likely to be able to use for the time constant circuit. Please contact us if you need a

detail information.

NOTE

1. Please make sure that your product has been evaluated in view of your specifications with our product

being mounted to your product.

2. You are requested not to use our product deviating from this specification.
