Mounting

The resistors are suitable for processing on automatic insertion equipment.

Marking

The resistors are marked with a 3 colour band code indicating the value.

The fourth band indicates the multiplier.

The fifth band indicates the tolerance.

Packaging

FRN25, FRN50S and FRN100S are normally supplied taped in 'ammo' boxes of 4,000 pieces.

FRN200S and FRN300S resistors are normally supplied taped in 'ammo' boxes of 1,000 pieces.

Other package styles available on request.

All tape specifications are in accordance with IEC 286-1.
