TE Connectivity (TE) is pleased to offer this unique High Power, metal chip
resistor for current sensing positions. It has a special metal resistive element
and suitable barrier layers beneath the solder to prolong terminal life. Following
the developments by semiconductor manufacturers in the production of a range
of IC's for battery charge management and low voltage power supplies, the TLR
Series satisfies the demand for a low ohmic shunt resistor to act as a current
sensor. It has particular applications in the automotive industry for sensing in
EMU's.

1. The cumulative tolerance of 10 sprockets hole pitch is ±0.2mm.
2. Carrier camber shall be not more than 1mm per 100mm through a length of 250mm.
3. A & B measured 0.3mm from the bottom of the packet
4. T measured at a point on the inside bottom of the packet to the top surface of the carrier.
5. Pocket position relative to sprocket hole is measured as the true position of the pocket and not
the pocket hole.
