The 0201WMF7323TEE from UNI-ROYAL / ROYALOHM is a general-purpose thick-film chip resistor with a 732kΩ resistance, ±1% tolerance, and 1/20W (50mW) power rating. Its miniature 0201 SMD package is suitable for high-density PCB assemblies and circuits requiring a relatively high resistance value with 1% accuracy.
According to the manufacturer’s ≤1% resistance coding system, 7323 means 732 × 10³Ω, or 732kΩ. The 0201 series supports ±1% and ±2% resistance values from 1Ω to 10MΩ.
The resistor uses the 0201 imperial / 0603 metric package, with nominal dimensions of approximately 0.60 ±0.03mm × 0.30 ±0.03mm × 0.23 ±0.03mm.
For the 0201 size, the manufacturer specifies a 25V maximum working voltage and 50V maximum overload voltage. The operating-temperature range is −55°C to +155°C, with power derating required at elevated ambient temperatures.
For 0201 thick-film resistors above 10Ω, the specified temperature coefficient is ±200ppm/°C. Therefore, the 732kΩ 0201WMF7323TEE uses the ±200ppm/°C TCR specification.
Construction includes a high-purity alumina substrate, thick-film resistive element, protective coating, nickel barrier termination, and lead-free outer tin termination. The standard series is suitable for both wave and reflow soldering.
The manufacturer’s performance specification lists an insulation resistance of at least 1,000MΩ. For ±1% products, resistance change after short-time overload is limited to ±(1.0% + 0.05Ω), while the rapid-temperature-change specification is ±(0.5% + 0.05Ω).
Because of its miniature dimensions, 0201 resistors have no resistance marking on the component body. Identification should therefore be based on the reel label, ordering code, BOM, or electrical measurement.
The full ordering number can be decoded as follows: 0201 identifies the chip size, WM indicates 1/20W, F indicates ±1% tolerance, 7323 represents 732kΩ, T indicates tape-and-reel packaging, the first E indicates 15,000 pieces, and the final E identifies the standard lead-free version.
UNI-ROYAL currently continues to list its general 0201 thick-film chip resistor family in its official product catalog. However, the public catalog does not expose a standalone Active/NRND/Obsolete lifecycle field for the exact 0201WMF7323TEE order code.
