CRH1206F1K50P05Z 1206 1.5K 0.5W Ever Ohms High-Power Resistor
Product Overview
The CRH1206F1K50P05Z is a high-power thick film chip resistor from Ever Ohms' CRH series. It features a 1206 package (3216 metric), a nominal resistance of 1.5KΩ, ±1% tolerance, 0.5W (1/2W) rated power, and a temperature coefficient of ±100PPM/°C. This model achieves higher power handling than conventional thick film resistors within the same 1206 footprint, making it suitable for circuit designs where power density and board space are critical.
Part Number Decoding
In the part number "CRH1206F1K50P05Z," "CRH" denotes Ever Ohms' high-power thick film chip resistor series; "1206" is the imperial package size (3.2mm × 1.6mm); "F" indicates ±1% resistance tolerance; "1K50" represents the 1.50KΩ nominal value; "P05" specifies the 0.5W power rating, distinguishing it from the standard 0.25W rating typical of 1206 thick film resistors; "Z" is the packaging and environmental compliance code.

The resistor uses a thick film screen-printing and high-temperature sintering process, with nickel barrier and tin-plated terminations, delivering a stable 0.5W power output in a 1206 footprint. Its operating temperature range covers -55°C to +155°C, accommodating diverse environmental conditions from consumer electronics to industrial control.
Performance Highlights
Ample power headroom. Conventional 1206 thick film resistors are typically rated at 0.25W. The CRH1206F1K50P05Z doubles this to 0.5W, providing a two-fold thermal budget within the same pad area. This allows direct drop-in replacement in existing 0.25W designs without layout changes, yielding a higher power safety margin.
Versatile 1.5KΩ value. 1.5KΩ falls within the E24/E96 standard resistance series and is widely used in voltage dividers, signal conditioning, and current-limiting circuits. It is readily available, reducing the risk of supply shortages during prototyping and mass production.
Derating consideration. Although rated at 0.5W, practical designs should account for derating. Operating at approximately 70% of the rated power (i.e., within 0.35W) is recommended for long-term reliability.
Typical Applications
The CRH1206F1K50P05Z is suitable for input/output current limiting in switching power supply modules, feedback voltage divider networks, balancing and sampling circuits in lithium battery PACK protection boards, current-limiting resistors in small motor driver boards, smart home control boards, and auxiliary circuits in charging stations. It is also applied in power management circuits across communication equipment, computer motherboards, and consumer electronics.
