What should engineers review before using WF04H1004BTL?

Verify the exact product-series datasheet. The supplied WFxxQ/R family document gives 0402 dimensions of 1.00 mm × 0.50 mm × 0.35 mm, but specifies a WF04 resistance range only up to 255 kΩ and does not establish that this H-series 1 MΩ MPN belongs to that series.

What is the pinout of WF04H1004BTL?

Use the WF04H1004BTL datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about WF04H1004BTL pinout to locate pins, power rails, and interface signals before layout.

AI summary

WF04H1004BTL is listed as a 1 MΩ ±0.1% 0402 chip resistor from Walsin. The supplied family datasheet supports the 0402 mechanical format, but does not clearly validate this exact H-series MPN or its 1 MΩ value.

Best for

Space-constrained precision resistor locations after exact-series verification
0402 surface-mount designs requiring 1 MΩ ±0.1%

Avoid if

The design requires verified TCR, power, voltage, or environmental ratings without an exact-MPN datasheet
The BOM cannot tolerate unresolved series-to-datasheet mismatch

Check before use

Confirm that WF04H1004BTL is covered by the supplied or a current Walsin datasheet
Confirm TCR and rated-power requirements for the exact ordering code
Validate the 1 MΩ value and ±0.1% tolerance through an authorized source
