Key Features
ISuperior quality metal
film resistors with 1%
tolerance and
temperature coefficients
down to 50 ppm. 3 case
sizes are available in
0.25, 0.6, 0.75W. The
LR1L series is a
low ohmic value range
from 0.1 to 0.82 ohm.
Ideally suited where low
resistance and small size
are required.
IMetal film resistors have
excellent stability under
load and severe
environmental
conditions. They exhibit
very low noise current
and voltage coefficients.
They are available in a
wide range of resistance
values and are suitable
for general purpose
and precision
applications.
The resistive element comprises a thin film of nickel-chrome alloy evaporated onto a high
thermal conductivity ceramic element. Metal end caps are force fitted to the element prior
to spiralling to value. Tinned copper lead wires are welded to the end caps and the
components are then coated. One coat of phenolic resin is followed by three coats of
epoxy resin. All resistors are tested for value and tolerance.

* For LR1L the limits are ± (5% + 0.1 ohm) and ± (1% + 0.05 ohm)
respectively. All resistance values are measured at a distance of 12mm
from the end cap.
Mounting
The resistors are suitable for processing on automatic insertion equipment and cutting and bending machines.
Marking
The resistors are marked with a colour band code in accordance with JIS C 0802.
Packaging
LR0204, LR1L and LR1 resistors are normally supplied taped in 'ammo' boxes of 4000 pieces.
LR2 resistors are normally supplied taped in 'ammo' boxes of 1000 pieces.
Other package styles on request.
All tape specifications are in accordance with IEC 286-1.
