Walsin’s 116-row multiplexer export shifts left from Pin Description onward. A naive read of pin count averages 50; corrected, it averages 6.1.

Walsin lists 72 real RF baluns, fixed at 50Ω unbalanced. Pick the balanced impedance ratio first — 100Ω, 50Ω, or one of five single-option parts.

Walsin inductors quote tolerance two ways: ±nH or ±%. 994 of 5,410 real parts use nH. Full value list, letter codes and the filter trap inside.

Resistor array vs discrete: resistance, tolerance and power usually carry over, TCR often does not. One Walsin array series proves it is not automatic.

Resistor TCR sets how much resistance drifts per degree. A series named for one TCR figure can ship a looser one. Real Walsin TCR bands, counted.

Nine of Walsin’s twenty thin film parametric exports return zero rows. The completion rate by series runs from 72.7% down to zero. Here is the count.

Walsin thin film resistor sizes run 0201 to 2512. Resistance ceiling does not scale smoothly: 0402 stops at 255 kilohm, a quarter of the 0603 limit.

Two of Walsin’s 13 chip resistor series groups publish E24 resistor values only; the rest, except current sense, mix E24 and E96 in every case size.

Walsin’s chip resistor resistance range tops out at four different ceilings depending on case size: 100 M, 22 M, 10 M or 1 M ohm, never one flat number.

Walsin WR and MR resistor dimensions are identical at every shared case size. The MR datasheet specifies 16 qualification tests against WR’s 8.
