WWXXC overview
WWXXC is a component documented by WALSIN TECHNOLOGY CORPO. The PDF description identifies it as "Low ohm chip resistors." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- The composition of the paste is adjusted to give the approximate resistance required and the value is trimmed to nominated value within tolerance which controlled by laser trimming of this resistive layer.
- dissipation at T amb =70 °C 1/2W 1/3 W 1/4 W 1/8 W 1/10 W Max.
- Example: R10 = 0.100 Ω 050 = 0.050 Ω FUNCTIONAL DESCRIPTION Product characterization Standard values of nominal resistance are taken from the E96 & E24 series for resistors with a tolerance of ±5% & ±1%.
- De-rating curve The power that the resistor can dissipate depends on the operating temperature; see Fig.2 MOUNTING Due to their rectangular shapes and small tolerances, Surface Mountable Resistors are suitable for handling by automatic pla.
- ASC_WWxxC_V07 Jan 2014 SOLDERING CONDITION The robust construction of chip resistors allows them to be completely immersed in a solder bath of 260 °C for 10 seconds.
- Surface Mount Resistors are tested for solderability at 245 °C during 3 seconds within lead-free solder bath.
- The test condition for no leaching is 260 °C for 30 seconds.
Topics covered by the datasheet
The document includes sections related to:
- DESCRIPTION
Engineering review checklist
- Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
- Derate continuous power for ambient temperature and verify pulse or surge capability separately.
- Match the land pattern, termination finish and current-sense routing to the exact package option.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
