CRH1206F160KP05Z Ever Ohms Resistor: 1206 160K 0.5W High-Power Thick Film Chip Resistor Technical Overview
1. Product Positioning and Brand Background
The CRH1206F160KP05Z is a high-power thick film chip resistor from Ever Ohms' CRH series. Founded in 1988, Ever Ohms is a veteran chip resistor manufacturer and one of the few companies that maintains thick film, thin film, and metal plate product lines simultaneously. The company holds ISO 9001, IATF 16949, and AEC-Q200 certifications, ensuring compliance with automotive and industrial quality standards.
The CRH series is designed to double the power rating within the same package size compared to standard CR thick film resistors. This makes the 1206 160K 0.5W resistor particularly suitable for circuit designs where PCB space is limited but higher power handling is required.

The 1206 160K 0.5W rating means this resistor delivers twice the power capacity of a standard 1206 thick film resistor (0.25W) without requiring PCB layout changes. This drop-in upgrade capability is a key advantage for engineers addressing thermal margin issues in existing designs.
4. Technical Features
High power density. The resistor utilizes a high-alumina ceramic substrate (Al₂O₃ ≥ 96%), ruthenium-based thick film resistive layer, and a three-layer termination structure (nickel barrier + tin plating) to achieve 0.5W in a standard 1206 footprint. The widened side electrode design enhances heat dissipation.
Thermal stability. The ±100PPM/°C TCR ensures stable resistance across the full operating range of -55°C to +155°C. For the 160KΩ value, this specification meets the requirements of most industrial control and power management circuits.
Reliability. The series passes 1000-hour damp heat testing at 85°C/85% RH with resistance drift below 0.5%. The three-layer termination structure provides robust solder joint reliability and reduces the risk of tombstoning during SMT assembly.
Surge capability. The thick film construction offers inherent short-term overload and surge resistance, making the CRH series suitable for power supply startup and load transient conditions.
5. Typical Applications
-
Power supply voltage dividers: The 160KΩ value is commonly used in DC-DC converter feedback networks; the 0.5W rating provides ample derating margin.
-
LED driver circuits: For voltage division and current setting, with high power density suitable for compact driver boards.
-
Industrial control equipment: Signal conditioning and power load functions in PLCs, inverters, and similar systems.
-
Automotive electronics: Available in AEC-Q200 compliant versions.
