High reliability chip resistors go to 50Gohm

The HR series of resistors is ideal for applications that require very high feedback division ratio in high gain amplifiers for instrumentation, test and measurement and medical equipment.

TT Electronics Welwyn Components has developed a family of high reliability chip resistors with a resistance range to 50Gohm.

Designated the HR series, this resistor range is ideal for applications that require very high feedback division ratio in high gain amplifiers for instrumentation, test and measurement and medical equipment.

John Graham, Sales and Marketing Director highlights: "Welwyn Components offer a key bespoke service for this family of resistors, of developing and adjusting the resistor for custom pulse applications, with terminations available for wire bonding or soldering".

This range of chips offers the designer low voltage coefficient of resistance and is available in four standard sizes 0503, 0805, 1005 and 1206.

With a resistance range from 10Mohm to 50Gohm, the high resistance value of these devices is such that power dissipation is always small, so they are rated only in terms of maximum voltage.

TCRs are available at 0 to 2500ppm/C with limiting element voltages of 50, 100, 150 and 200V.

The operating temperature range is -55 to +125C, with a resistance tolerance to 5%.
