Resistor Taping Specifi cations & Mechanical Characteristics
TAPE TAPE DIMENSIONS (mm)
MECHANICAL CHARACTERISTICS
LEAD PULL TEST
The lead wire shall withstand steady pull of the following weight axially to the lead wire for the minimum period of 10 seconds
without any breakage or damage:
LEAD BEND TEST
The lead wire shall withstand minimum 4 bends of 90o rotation without any breakage or damage, when the resistor is placed in a
vertical position and is applied with a weight of 0.5Kgs for 0.4 - 0.5omm or 1.1Kgs for 0.6omm and over lead wire.
SOLDERABILITY
The lead wire is immersed into 10% methanol or isopropyl alcohol of rosin by weight for a period of 2 ± 0.5 seconds. Then, it shall
be dipped into molten solder melted at 230 ± 5oC for a period of 5 ± 1 seconds approximately 1.5mm from the body of the resistor.
A new adhering coating of solder shall cover minimum 95% of the surface being dipped into solder.
RESISTANCE TO CLEANING SOLVENTS
Color coating or marking shall remain legible after cleaning by solvents such as isopropyl alcohol, trichloroethylene, freon®
TF/TAX, xyliene etc., in form of liquid or gas.
