RN73H1J (0603) Ultra Precise Thin Film Chip Resistors

 

Featuring a moisture-resistant protective layer over the resistive film construction, the RN73H1J offers enhanced moisture resistance (85ºC+2ºC, 85%+4% RH, 1000 hrs). 

With a precision tolerance of +/-0.05% ~ +/-1.0%, a resistance range of 10Ω ~ 1MΩ, power rating of 1/10W and T.C.R. values of +/-5 ~ +/-100ppm/ºC, the 0603 package RN73H thin film resistor is designed for applications that require a reliable resistor for humidity and high temperatures to 155ºC. The RN73H1J is AEC-Q200 Qualified.

RN73H1J chip resistors are ideal for applications within the transportation, medical, telecommunications, consumer electronics and industrial markets, especially in applications where high temperature/high humidity are a concern.

Other sizes of the KOA Speer's RN73H chip resistor series include 0402, 0805, 1206 & 1210 and feature a power rating range of .063W to .25W, resistances up to 1MΩ and maximum working voltages between 50V and 400V. The RN73H series are available with lead-free terminations to meet EU RoHS requirements.

TPR Series: Temperature Protection Fusing Resistors

 

TPR series resistors safely interrupt open circuits up to AC250V voltage and completely isolate the circuit after quickly fusing to the overload. These fusing resistors feature the pulse capability of wirewound resistors and are approved by UL1412 safety standards. 

With a wide operating temperature range of -40ºC ~ +150ºC and 1 Watt power rating, TPR series fusing resistors are ideal for AC adaptors, small size switching power supplies, and lighting equipment (LED). These fusing resistors are available in 2Ω~10kΩ resistance values at 5% tolerance. TPR resistors are also lighting surge compliant (IEC61000-4-5).

RN73H1E Ultra Precision Chip Resistor

 

- 0402 (1E) size of the RN73H line of Ultra Precision Chip Resistors

These thin film (metal) chip resistors feature high heat resistance (up to +155ºC) and ultra high precision (±0.1%) tolerance. The RN73H offers enhanced moisture resistance (85°C ±2°C, 85% ±4% RH, 1000h) by the use of a special protective layer over resistive film construction.

The RN73H1E chip resistor also features a power rating of 1/16 (0.063) Watts and TCR values of ±10 ~ ±50 ppm/°C. The 0402 (1E) offers a precision tolerance of 0.1% ~ 1.0% and a resistance range of 10Ω ~ 300kΩ. Additionally, the RN73H1E is AEC-Q200 qualified and is available with lead-free terminations to meet EU RoHS requirements.

Used primarily as reliable precision resistors that are robust to humidity and high temperature (+155ºC), RN73H1E chip resistors are ideal for applications within the transportation, avionics and medical markets, specifically any applications where high temperature/high humidity are design considerations.

KOA Speer's RN73H chip resistor series is available in a range of sizes, from 0402 (1E) to 1210 (2E). These chip resistors feature a power rating range of .063W to .25W, resistances up to 1MΩ and maximum working voltages between 50V and 400V.
