RM06F9530CT Спецификация: 0603 953Ω 1% Характеристики и данные испытаний

2026-05-25 22

Measured across production lots, a properly specified 0603 953Ω 1% chip resistor should remain within ±1% resistance tolerance under standard conditions. This article breaks down datasheet values and lab-verified expectations for designers using RM06F9530CT as the reference part.

(1) Product Overview & At-a-Glance Specs

RM06F9530CT is offered in the 0603 (1608 metric) case. Designers should record package code and power class in BOMs to match footprint and thermal constraints.

Nominal R	Tolerance	Case	Typical Power	TCR Class	Op. Temp
953 Ω	±1%	0603 (1608 M)	0.10 W	±50 ppm/°C	-55°C to +125°C

(2) Electrical Limits & Temperature Behavior

Resistance & Tolerance Details

A nominal 953 Ω resistor at ±1% tolerance permits an allowable range of 943.47 Ω to 962.53 Ω. This informs acceptance criteria for incoming inspection.

TCR and Thermal Drift

TCR drives resistance drift with temperature. A reference of ±50 ppm/°C implies a drift of approximately 47.65 mΩ/°C for a 953 Ω value.

Temp (°C)	ΔR (Ω) @ ±50 ppm/°C	Resulting Resistance
+25	0	953.00 Ω
+125	+4.765	957.76 Ω
-55	-3.863	949.13 Ω

(3) Test Data & Performance Benchmarks

Reproducible test protocols are required to validate datasheet claims. Standardized tests—including DC resistance and load-life—ensure procurement reliability.

Test Type	Conditions	Mean ΔR (%)	Pass Rate
Initial DC R	25°C, n=50	0.00%	100%
Load Life	70°C, 1000 h	0.60%	96%
Solder Heat	260°C, 10s	0.15%	100%

(4) Application & Sourcing Guidance

When substituting RM06F9530CT, match resistance, tolerance, case, TCR, and power. Apply the datasheet derating curve to determine allowable continuous power at high board temperatures.

What acceptance range should be used for RM06F9530CT incoming inspection?

Use the nominal ±1% tolerance range: 943.47 Ω to 962.53 Ω measured at ambient conditions, with calibrated equipment and corrected lead resistance; flag lots with >5% out-of-spec rate.

How should we verify the TCR for a 0603 resistor in our lab?

Measure resistance at three or more stabilized temperatures (e.g., 0°C, 25°C, 85°C), compute ppm/°C slope, and compare to the datasheet TCR entry; ensure thermal equilibration and avoid self-heating.

Which reflow profile criteria matter most for 0603 953Ω 1% specs?

Follow the component reflow curve in the datasheet: control time above liquidus, peak temperature within limits, and ramp rates to mitigate soldering damage and tombstoning.

What is the typical power derating for RM06F9530CT?

Power typically derates linearly from 100% at 70°C board temperature to 0% at 125°C or 155°C, depending on the specific substrate and environmental conditions.
