CRH1206F91R0P05Z 1206 91R 0.5W SMD Resistor — Professional Overview
1. Product Overview
The CRH1206F91R0P05Z is a high-power thick film chip resistor from Ever Ohms' CRH series, housed in a standard 1206 package (3.2mm × 1.6mm metric 3216). It features a nominal resistance of 91Ω (91R), a rated power of 0.5W (1/2W), a tolerance of ±1%, and a temperature coefficient of ±100PPM/℃. As a 1206 91R 0.5W SMD resistor, this model delivers twice the power rating of conventional thick film resistors in the same footprint, making it suitable for circuits with defined power dissipation and thermal requirements.
2. Part Number Decoding
The part number CRH1206F91R0P05Z follows Ever Ohms' standardized naming system:
| Field | Value | Meaning |
|---|---|---|
| Series | CRH | High-power thick film chip resistor |
| Size | 1206 | Imperial 1206 (metric 3216) |
| Tolerance | F | ±1% |
| Resistance | 91R0 | 91.0Ω (R denotes decimal point) |
| Power | 05 | 0.5W |
| Suffix | Z | Halogen-free, RoHS compliant |
The CRH series represents Ever Ohms' high-power product line, developed through optimized ceramic substrate thermal pathways, refined resistor paste formulations, and enhanced electrode heat dissipation structures to double the power rating compared to standard thick film resistors in identical package sizes.
3. Core Electrical Specifications
| Parameter | Specification |
|---|---|
| Series | CRH (High-Power Thick Film) |
| Package | 1206 (3.2mm × 1.6mm) |
| Nominal Resistance | 91Ω (91R) |
| Tolerance | ±1% |
| Rated Power | 0.5W (1/2W) |
| Temperature Coefficient | ±100PPM/℃ |
| Operating Temperature | -55℃ to +155℃ |
| Environmental | RoHS compliant, halogen-free |
The 91Ω value of this 1206 91R 0.5W resistor positions it well for voltage division, bias setting, and moderate current loop applications. The combination of ±1% tolerance and ±100PPM/℃ TCR ensures resistance stability across the full operating temperature range. The 0.5W power rating provides twice the thermal margin of standard 1206 resistors (typically 0.25W), resulting in lower temperature rise under full load and improved long-term reliability.
4. Technical Features
High Power Density. Through thick film process optimization, the CRH1206F91R0P05Z achieves 0.5W in a 1206 footprint. Designers can handle greater power dissipation without increasing PCB real estate, reducing constraints imposed by derating requirements.
Resistance Stability. The ±100PPM/℃ TCR represents good control within the CRH series. For a mid-range value like 91Ω, temperature-induced resistance shifts remain manageable for most circuit functions requiring signal accuracy.
Thick Film Reliability. Thick film construction provides inherent pulse current withstand capability, performing reliably under switching surges and load transients. The model complies with RoHS directives and contains no REACH SVHC substances, meeting environmental requirements for export electronics.
5. Typical Applications
The 1206 91R 0.5W SMD resistor suits signal division and bias circuits in switching power supplies and DC-DC converters; current limiting and voltage division nodes in industrial control power stages; current setting and feedback networks in LED driver circuits; and auxiliary sampling loops in consumer electronics adapters. For designs requiring elevated power dissipation within a 1206 footprint, the CRH1206F91R0P05Z is a practical selection.
