®
Foil resistors are not restricted to standard
values, we can supply specific “as required” values at
no extra cost or delivery (e.g. 1K2345 vs. 1K)
• Fast thermal stabilization <1 s
Electrostatic discharge (ESD) up to 25 000 V
• Short-time overload: ≤0.02%
• Non-inductive, non-capacitive design
• Rise time: 1 ns effectively no ringing

• Non-inductive: <0.08 μH
• Non-hot-spot design
• Terminal finish: tin/lead alloy
• Matched sets are available on request
• For prototype units, append a “U” to the model number
(example: 303134U). These units have all of the table
2A (page 4) 100% tests performed, with no destructive
qualification testing required (table 3A, page 4). For

INTRODUCTION
The 303133 through to 303138 series is the first surface
mount device to provide high rated power, excellent
load-life stability along with extremely low TCR all in one
resistor.
One of the most important parameters influencing
stability is the temperature coefficient of resistance (TCR).
Although the TCR of foil resistors is considered extremely
low, this characteristic has been further refined over the
years. The 303133 through to 303138 series utilizes ultra
high-precision Bulk Metal
®
Z-Foil. The Z-Foil technology
provides a significant reduction of the resistive element’s
sensitivity to ambient temperature variations (TCR) and
to self-heating when power is applied (power coefficient).
Along with the inherently low PCR and TCR, Z-Foil
technology also provides remarkably improved load-life
stability, low noise and availability of tight tolerance.
The 303133 through to 303138 series has a full
wraparound termination which ensures safe handling
during the manufacturing process, as well as providing
stability during multiple thermal cyclings.
Our application engineering department is available to
advise and make recommendations.
