0.1W 1kΩ ±1% Tolerance Thick Film Chip Resistor High Power SMD Resistor for

In high-density electronics—smartphones, wearables, compact chargers, and miniature sensors—the 0402 package has become the de facto standard for signal conditioning and power management. The CRH0402F1K00Q10Z from EVER OHMS (Tianer Technology) stands out as a flagship 1kΩ/0.1W component within the CRH high-power thick film chip resistor family. At a mere 1.0 mm × 0.5 mm footprint, it delivers nearly 60% more rated power than a conventional 0402 thick film resistor, striking an elegant balance between miniaturization and reliability.

EVER OHMS follows a segmented alphanumeric coding convention. Every character in CRH0402F1K00Q10Z carries a specific engineering meaning:

• CRH – High-power thick film series; the “H” signals an upgraded resistive paste formulation with tighter TCR control.
• 0402 – Package size, metric 1005, approximately 1.00 × 0.50 × 0.30 mm.
• F – ±1% tolerance.
• 1K00 – 1000Ω (1kΩ), with “K” denoting the kilo multiplier.
• Q – Paper tape packaging for 0402.
• 10 – Standard 7-inch reel quantity code.
• Z – Lead-free, halogen-free, RoHS compliant.

Rated at 0.1W (1/10W) at a 70°C ambient baseline, the CRH0402F1K00Q10Z pushes the envelope of what a 0402 form factor can handle—a roughly 59% gain over the standard 1/16W (0.0625W) CR series. This leap comes from three coordinated engineering advances:

1. Optimized alumina ceramic substrate for uniform heat dissipation.
2. Enhanced metal-oxide resistive paste with a film thickness around 100 µm.
3. Three-layer terminal electrodes—silver/silver-palladium inner layer, nickel barrier, tin outer layer—ensuring solder reliability and current-carrying capacity.

A glass glaze overcoat provides long-term sulfuration resistance, critical for wearable devices and appliances operating in humid or sealed environments.

• Tolerance±1%
• TCR±200 ppm/°C (−55°C to +125°C)
• Rated Power0.1W at 70°C; derating required above 70°C
• Max Working Voltage50V DC, 100V transient
• Operating Range−55°C to +125°C
• Reliability≤0.5% resistance shift after 1,000 hours at elevated temperature load

At 1kΩ, this resistor sits squarely in the signal division, current limiting, and reference matching sweet spot. Under 50V, actual dissipation is only about 2.5 mW—far below the 0.1W ceiling. Its real advantage is the thermal headroom and long-term drift margin packed into the tiniest footprint.

• TWS earbuds, smartwatches, and portable power banks (voltage division, LED limiting)
• Fast-charger auxiliary feedback loops
• Sensor signal conditioning in humid environments
• Portable instrumentation and compact PLCs

Precision current sensing or milliohm-level shunt applications. For those, EVER OHMS TRL metal film or alloy shunt resistors are the correct choice.

High-volume 0402 components are susceptible to refurbished and mixed-batch contamination. Sourcing through authorized channels with traceable lot data is non-negotiable.

EVER OHMS’ authorized Level-1 distributor in mainland China, with a partnership dating back to 2017 and a valid 2026 authorization certificate (TWD202601E0000122). Located at 7F, Building 9, Baoneng Science & Technology Park, Qingxiang Road, Longhua District, Shenzhen, they stock the full CRH range, support orders from 10 pieces to full reels, and provide FAE-level power calculations, thermal assessments, and BOM optimization—ideal for industrial, automotive, and medical-grade production runs.

Shunhai’s online procurement platform, offering real-time CRH0402F1K00Q10Z inventory, downloadable datasheets (EVER_CRH.pdf), tiered pricing, and single-piece ordering—perfect for prototyping, urgent replenishment, and multi-part sampling.

With no marking on the 1.0 × 0.5 mm body, identification relies entirely on reel labels. Use symmetric stencil apertures, cap reflow at 260°C peak, and watch for tombstoning. Conduct four-wire LCR sampling, power-load aging, and thermal cycling on first-article inspection before volume release.
