General Purpose Resistors with Customized Service

Token Electronics is expanding business to include a broad range of General Purpose Resistor products

designed for high volume applications. This expanded range of commercial resistor presents a more

comprehensive product offering for Customer Experience Management (CEM) and other high volume

customers that require quality products at competitive pricing.

Backed by the same customer service, technical support and quality assurance that Token has always

provided, these new commercial products enable you the opportunity to source a wider range of

resistors from a trusted supplier.

General Use

When an ambient temperature exceeds a rated ambient temperature, resistor shall be applied on the

derating curve by derating the load power. General purpose resistor under overloads is not combustion

resistant and is likely to emit, flame, gas, smoke, red heat, etc. Flame retardant resistor generally emits

smoke and red heat in a certain power and over but do not emit fire or flame.

When resistors are shielded or coated with resin etc., stress from the storage heat and the resins are

applied. So, performance and reliability should be checked well before use.

When a voltage higher than rated is applied in a short time (single pulse, repeated pulses, surge, etc.), it

does not necessarily ensure safety that an effective wattage is not higher than a rated wattage. Then

consult with us with your specified pulse wave shape. Resistors shall be used in a condition causing no

dew condensation.

Keep temperature from rising by choosing resistor with a higher rated capacity; do not use a

component having the exact load value required. For considerations of safety in extended period

applications, the rating should be more than four times higher than the actual wattage involved, but

never use resistors at less than 25% of its rated power.

In applications where resistors are subject to intermittent current surges and spikes, be sure in advance

that the components selected are capable of withstanding brief durations of increased load.

Do not exceed the recommended rated load. Resistor must use within the rated voltage range to

prevent the shortening of service life and/or failure of the wound resistance elements.

Minimum load: Resistor must be utilized at 1/10 or more of the rated voltage to prevent poor

conductance due to oxidation build-up. For basic particulars for cautions, refer to EIAJ Technical

Report RCR-2121 "Guidance for care note on fixed-resistors".
