Carbon Film Resistors

Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or 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. Keep the rated power and ambient temperature within the specified derating curve.

* When positioning and mounting Carbon Film Resistors (hereafter called the resistors), make allowance for the effect

of heat generated through close contact between the resistors and neighboring components and for the

temperature rise of adjacent heat-generating components.

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.

When applying pulses to the resistors, keep the pulse peak within the rated voltage.

3. When the resistors' protective coatings are chipped, flawed, or removed, the characteristics of the resistors may be

impaired. Take special care not to apply mechanical shock during automatic mounting or cause damage during

handling of the boards with the resistors mounted.

4. Ultrasonic cleaning may cut the lead wire due to resonance. Try and check it before use.

5. Flame-retardant type

1) Take special care in handling the flame-retardant type because it is covered with a special coating and is therefore

by more susceptible to external shock and solvent damage than other regular types of the resistors.

2)The external coating used for the flame-retardant type is not resistant to solvent. Take great care in using solvent.

If problems are anticipated, then take appropriate preventive measures, such as mounting the resistors after

solvent is used.
