Type S Series

Tyco introduces a range of surface

mount power resistors to meet

today's circuit design needs. One

design concept allows an engineer

to

choose

from

three

styles

(Lo Ohm, Power, or Ultra Precision)

while

staying

within

the

new

standard circuit board land pattern

guidelines now accepted by the

wirewound resistor industry. Each

size offers low profile case design

with

flexible

tinned

copper

terminations for

reliable solder

joints. All styles utilise a fully

welded

construction

technique,

unlike other designs that rely solely

on tinned termination connections.

These

features

allow

the

S

Series to withstand the higher

temperatures

associated

with

reflow, vapour phase, or infrared

(IR)

manufacturing

processes

without degradation.

Key Features

■ Low Profile Design

■ Available on Tape

(3 Reel Sizes)

■ Very Wide Value Range

■ Ideal for Current Sensing

■ Up to 3.0 Watts Power

■ High TCR Versions

(to 6000ppm)

■ Stable to 5ppm/°C
