CRT0805-BY-3321ELF is a thin-film precision chip resistor designed for current sensing, precision circuits, and demanding applications in medical equipment, printers, automation, and navigation systems. The device features ultra-tight tolerance with a resistance tolerance of ±0.1% (B code) and a temperature coefficient of resistance (TCR) of ±25 PPM/°C (Y code), ensuring exceptional stability across temperature variations. It is rated for 1/8 watt power at 70°C with a maximum working voltage of 150 V and maximum overload voltage of 300 V, supporting resistance values from 24.9 to 332 kO depending on tolerance grade. The resistor operates over a temperature range of -55°C to +155°C and features RoHS-compliant tin-plated termination. Its compact 0805 package dimensions (2.00 ± 0.15 mm length, 1.25 ± 0.15 mm width, 0.55 ± 0.10 mm height) make it ideal for space-constrained applications requiring high precision and reliability.
