LOW-RESISTANCE, HIGH-POWER RESISTOR HAVING A TIGHT RESISTANCE TOLERANCE DESPITE VARIATIONS IN THE CIRCUIT CONNECTIONS TO THE CONTACTS

摘要

A tight-tolerance, low-resistance, high-power chip resistor for mounting on a circuit board (14) in parallel and adjacent relationship to such board. There are discrete terminal plates (11, 12) mounted on one surface of a substrate (10) in spaced-apart relationship to each other but still quite close to each other. Electrical connections are made by the customer to the terminal plates (11, 12), at different regions thereof, without adversely affecting the tight-tolerance relationship. The terminal plates (11, 12) additionally provide heat spreading from the resistance film (25), enhancing the power handling capability of this low-resistance, high-power chip resistor.
