0603 Package 620Ω Resistance 0.125W Rated Power High Power Thick Film Chip Resistor for Power-Sampling Circuits

1. Part-Number Breakdown

CRH0603F620RP05Z is the full ordering code of the Ever Ohms CRH series thick-film high-power chip resistor. Reading it segment by segment: CRH denotes Thick Film High Power Chip Resistor (a higher-power variant above the standard CR line); 0603 is the imperial 1608 metric package, 1.6 mm × 0.8 mm; F stands for ±1% tolerance; 620R is the nominal resistance of 620 Ω; P05 indicates 5-inch tape-and-reel packaging; the trailing Z means lead-free and RoHS compliant. When a BOM calls out a 0603 620R 0.125W Ever Ohms resistor, this is the exact part—no further package or power conversion is needed.

2. Key Electrical Specifications

This 0603 620R 0.125W Ever Ohms resistor is rated at 1/8 W (0.125 W at 70 ℃ ambient), 620 Ω ±1%, with a temperature coefficient of ±100 ppm/℃. The CRH0603 size carries a maximum working voltage of 75 V; for 620 Ω, which falls in the 330 Ω–1 kΩ band, the short-time overload voltage is approximately 600 V for 5 seconds. The terminals use a nickel barrier with pure tin plating, compatible with lead-free reflow up to 260 ℃ peak, and the tape-and-reel format feeds directly onto SMT lines.

3. Typical Applications

Parts like CRH0603F620RP05Z are commonly found in current-sensing dividers on power modules, DC-DC feedback networks, LED constant-current drivers, battery-protection detection circuits, instrumentation signal conditioning, and pull-up/pull-down or current-limiting branches on industrial control boards. Compared with generic thick-film resistors in the same package, CRH raises the 0603 rating from a typical 1/10 W to 1/8 W—either lowering the derating ratio at a given heat load or allowing larger pulses under the same derating. It is also widely used in fast-charging protocol boards, home-appliance control boards, and smart-home modules.

4. Product Advantages

First, high power density: 0.125 W inside a 0603 footprint suits space-constrained portable and densely packed boards. Second, stable precision: ±1% tolerance with ±100 ppm/℃ keeps divider-ratio drift predictable across the industrial temperature range, reducing error accumulation at amplifier inputs. Third, robust soldering: the alumina substrate and nickel-barrier terminal structure resist copper migration and sulfuration under lead-free processes, with lower long-term high-temperature drift than comparable general-purpose parts. Fourth, full compliance: the part meets RoHS and REACH, is lead-free and halogen-free, and can directly enter EU- and US-bound system supply chains.

5. Market Positioning

Within the 0603 high-power resistor segment, the CRH line sits in the strong value-for-money tier among Taiwanese second-tier manufacturers—matching Japanese equivalents in electrical specs while offering better price and lead time (typically measured in weeks). CRH0603F620RP05Z targets cost-sensitive industrial and consumer customers that cannot accept the insufficient derating of ordinary 1/10 W parts, and is a frequent choice for domestic-substitution and second-source programs.
