markdown100 nF Capacitor 0603 - Walsin 0603B104J500CT
Walsin Technology Corporation 0603B104J500CT: 0603 MLCC, 100 nF ±5% X7R, 50 V. An Adom Basic Part: Adom keeps it on reels for its pick-and-place line, so boards built with it draw on Adom stock.
Key specs
| Spec | Datasheet |
|---|---|
| 0603 (1608 metric) multilayer ceramic chip capacitor, 1.60 × 0.80 × 0.80 mm body (+0.15/−0.10 mm, thickness code X), 0.40 mm termination bands; reflow or wave soldering | p.3 |
| 100 nF ±5% (code 104 J), rated 50 VDC, X7R Class II dielectric, code B; listed in the X7R capacitance-range grid at 0603 / 50 V | p.2, p.7 |
| X7R temperature characteristic: capacitance within ±15% from −55 to +125 °C | p.4, p.14 |
| Dissipation factor ≤3% at 1 kHz / 1.0 Vrms; Class II parts get a 150 °C / 1 h de-aging plus 24 h rest before any measurement | p.4, p.12 |
| Insulation resistance 10 GΩ or R×C ≥ 500 Ω·F, whichever is smaller, at rated voltage | p.14 |
| Dielectric strength: withstands 250% of rated voltage for 1-5 s with no damage or flashover | p.13 |
| High-temperature load life: 1,000 h at 125 °C and 200% of rated voltage; capacitance change within ±12.5% | p.18 |
| BaTiO3-based ceramic, Ni inner electrodes, Cu/Ni/Sn termination (code C, pure-Sn outer plating) | p.2, p.20 |
| Paper carrier tape, 8 mm wide / 4 mm pocket pitch, 4,000 pcs per 7-inch (φ178 mm) reel, code T; store at 5-40 °C / 20-70% RH, MSL 1 | p.11, p.19, p.20 |
Notes for designers
0603B104J500CT is a 0603 X7R capacitor from Walsin's General Purpose series: 100 nF ±5%, rated 50 VDC, decoded from the ordering table and confirmed in the X7R range grid. (p.2, p.7) It is a BaTiO3-based Class II ceramic, the approval sheet requires a 150 °C de-aging and 24 h rest before capacitance is even measured, a reminder that the label value is history- and drive-level-dependent. (p.4, p.20)
The numbers you design against: capacitance within ±15% from −55 to +125 °C, (p.4, p.14) dissipation factor ≤3% at 1 kHz / 1.0 Vrms, (p.12) insulation resistance 10 GΩ or R×C ≥ 500 Ω·F, (p.14) and a dielectric proofed at 250% of rated voltage. (p.13) Life testing runs 1,000 h at 125 °C and 200% of rated voltage with capacitance held within ±12.5%. (p.18) It ships 4,000 to a 7-inch paper-tape reel and is MSL 1. (p.11, p.20)
Footprint
The datasheet has no land pattern, so the pads are the IPC-7351 nominal pattern (KiCad's standard Capacitor_SMD:C_0603_1608Metric), replacing pads that were off it by up to 0.05 mm.
Source: IPC-7351 nominal (no land pattern in the datasheet): KiCad 10 Capacitor_SMD:C_0603_1608Metric pads.
| mm | Datasheet | KiCad standard (C_0603_1608Metric) | Previous | This page |
|---|---|---|---|---|
| Pad length (along the part) | none given | 0.9 | 0.9 | 0.9 |
| Pad width | none given | 0.95 | 1 | 0.95 |
| Gap between pads | none given | 0.65 | 0.7 | 0.65 |
| Centre to centre | none given | 1.55 | 1.6 | 1.55 |
| Overall | none given | 2.45 | 2.5 | 2.45 |
| Corner radius | none given | 0.225 (ratio 0.25) | 0.225 (ratio 0.25) | 0.1 (ratio 0.1111) |
Corners: KiCad roundrects with the radius held to 0.25 x the smaller pad side and no more than 0.1 mm (IPC-7351C favours rounded corners for paste release); copper area within 1 % of a square-cornered pad.
Chip outline
The part's 3D outline in the standard pose (pad 1 toward the viewer), drawn from the STEP by Adom's OpenCascade service; the part number sits where the laser-etched mark is on the 3D model and reads the same way.
Symbol options
The default symbol is the plain standard symbol. 0603B104J500CT-outline.kicad_sym adds the chip outline beside it; the widget below builds other layouts in the browser and never changes the default.
