MSASH168SC7224KTCA01

Taiyo Yuden MSASH168SC7224KTCA01: MLCC 0.22 uF +/-10 %, 100 V, X7S, 0603 (1608 metric). A medium-high voltage multilayer ceramic capacitor from Taiyo Yuden's MSAS general purpose series, previously sold as HMK107C7224KA-TE. Taiyo Yuden names inverters and DC/DC converters as its main applications.

DC bias: plan for the capacitance you get at your voltage

X7S is a class 2 dielectric, so the capacitance falls as DC voltage is applied. Taiyo Yuden's characteristics sheet plots it: read off that graph, the capacitance is roughly 30 % lower at 20 V, 60 % lower at 40 V, 80 % lower at 60 V and close to 90 % lower at the 100 V rating (values read from the plotted curve, not printed numbers). The same sheet gives capacitance and impedance against frequency, the temperature curve and ripple current heating.

Ordering

Stock figures are a snapshot from the Adom parts search on 2026-10-21; check the distributor before ordering. DigiKey listed the part with no stock that day; Mouser had 3,875. JLCPCB/LCSC search for MSASH168SC7224KTCA01 returned no part on 2026-10-21. Mouser also lists the previous part number HMK107C7224KA-TE and points it to this one.

Pins

A ceramic capacitor has no polarity: either terminal may face either way.

Land pattern: KiCad footprint vs Taiyo Yuden

Land pattern

The footprint is KiCad's standard `C_0603_1608Metric`, and this guide lays its pads over the land Taiyo Yuden publishes for this part as a DXF, at true scale. KiCad's pads are larger on every side and contain the maker's land. Use it to decide whether to keep the KiCad pads or change them to Taiyo Yuden's 0.6 x 0.8 mm lands before layout. The comparison, with the numbers

3D model

The model is Taiyo Yuden's own STEP for this part number, downloaded by plain HTTP from the product page and used with its bytes unchanged: it is already in millimetres, Z-up, seated on z = 0 and centred, so no transform was needed. It is 1.60 x 0.80 x 0.90 mm with 0.35 mm terminal bands; the 0.90 mm height is the top of the printed range (T 0.8 +/-0.10 mm, and the characteristics sheet says 0.9 mm max). The body colour is the maker's dark grey (their product photo shows a brown body); it was left as supplied. The part is unmarked, so no marking is shown.

The page viewer shows msash168sc7224ktca01-hero.glb: the clean model plus nonphysical reference artwork drawn under it to the adom-hero standard (adom/component-hero): the footprint's pads as teal dashed outlines at 50 % opacity, its silkscreen at 70 % transparency and the pad numbers 1 and 2. The part is non-polar, so no pin-1 dot is added. The artwork never goes into the STEP, package-reference.glb or the board LODs.

Model checked against the printed dimensions

The model was rendered in orthographic top, bottom, side and end views at true scale and laid over a drawing made at the same scale from the printed limits (nominal outline, tolerance limits, allowed terminal band). Every dimension is inside the printed range: L 1.600 mm (1.50 to 1.70), W 0.800 mm (0.70 to 0.90), T/H 0.900 mm (0.70 to 0.90), e (terminal band), top 0.350 mm (0.10 to 0.60), e (terminal band), bottom 0.350 mm (0.10 to 0.60).

Source: product page and catalog p.5, MSAS 16 thickness code 8 (tolerance code S): L 1.6 +/-0.10, W 0.8 +/-0.10, T 0.8 +/-0.10, e 0.35 +/-0.25 (mm); characteristics sheet: t = 0.9 mm max.

Board levels of detail

Clean board-use GLBs (no footprint pads, outlines, labels or silkscreen) in four levels, all in the same Z-up, metre, footprint-origin pose as the STEP. Previews are rendered from each GLB.
