0402 Package 22.6kΩ Resistance 0.1W Power Rating Thick Film Chip Resistor High

The CRH0402F22K6Q10Z belongs to the CRH high-power thick film chip resistor family from EVER OHMS. Every segment of the part number carries a defined specification:

This is what engineers shorthand as the 0402 22.6kΩ 0.1W Ever Ohms resistor — a 0402-footprint, 22.6kΩ, ±1%, 1/10W component.

The standard 0402 thick film resistor (Ever Ohms CR series) is rated at just 1/16W (0.0625W). The CRH series lifts this to 0.1W on the identical footprint — a ~59% gain achieved through ruthenium-based resistor paste, a thickened film layer (~100μm), and redesigned electrode thermal architecture.

For this 22.6kΩ variant:

• Rated current: I = √(0.1 / 22600) ≈ 2.1mA
• Theoretical rated voltage: U = √(0.1 × 22600) ≈ 47.5V
• Hard ceiling: 50V max working voltage, 100V surge

The 47.5V calculated limit sits dangerously close to the 50V ceiling — meaning power and voltage constraints arrive nearly simultaneously in this resistance range. Unlike 2MΩ variants where voltage caps out far before power is exhausted, here both must be verified in tandem.

The CRH series specifies TCR by resistance range: the kΩ band typically carries ±100ppm/°C (with some high-resistance segments reaching ±200ppm/°C). Over a 60°C swing (25°C to 85°C), this yields ~0.6% drift, which combined with the ±1% initial tolerance produces a worst-case window near ±1.6%.

The 0.1W rating is calibrated at 70°C ambient, continuous full load. Above 70°C, derating applies linearly:

At 100°C this drops to ~65mW; at 125°C only ~35mW remains. For positions near power semiconductors or inside enclosed housings, add another 1.5× to 2× derating margin. Best practice: keep sustained dissipation at 50–60% of rating.

As an E96 precision value, 22.6kΩ appears only where designers have done the math:

• Power supply feedback dividers — ±1% tolerance maps directly to output voltage error; thermal drift must be budgeted.
• Op-amp and comparator bias/hysteresis networks — sets gain and thresholds with tight stability needs.
• ADC front-end attenuation and level shifting — provides calibrated division ratios.
• RC timing and soft-start delays — paired with nF–μF capacitors for ms-to-hundred-ms constants.

These applications typically dissipate milliwatts or less, so the 0.1W rating delivers thermal headroom and transient resilience rather than raw heat-sinking capacity.

The 0402 is the most tombstone-prone package in existence. Pad geometry must be symmetric; stencil apertures require fine control, and excess paste will literally flip the part. Reflow peak must stay under 260°C per J-STD-020.

Thermal management relies entirely on pad-to-copper conduction. Extend copper pours on both sides of the pad, add thermal vias, and ensure solder joint integrity — any void or misalignment directly erodes the power rating. For high-resistance divider nodes, clean flux residues and consider solder-mask isolation trenches to prevent surface leakage. Bake components if stored in humid conditions before reflow to avoid micro-cracking.

Upgrading from a standard 0402 22kΩ 1/16W to CRH0402F22K6Q10Z is a straightforward drop-in: pads match, board stays untouched, thermal margin grows by ~59%. Downgrading requires full worst-case power re-verification. When cross-referencing other brands, align five parameters simultaneously — power, TCR, max working voltage, surge rating, and temperature range. Never rely on just three.

The 0402 22.6kΩ 0.1W Ever Ohms resistor is a high-volume commodity part, making counterfeits and refurbished mixes a real threat. Procurement must flow through authorized channels with full batch traceability.
