Product Overview
For a 3900 pF (3.9 nF) position on 1206 pads, Panasonic's ECUV1H392KBM brings X7R dielectric, a 50 V DC rating and +/-10 % tolerance in a multilayer ceramic chip. The final M in the number marks the thin 1206 body, 0.65 mm maximum height.
Key Features
- Capacitance: 3900 pF (3.9 nF, 0.0039 uF), code 392
- Rated voltage: 50 V DC (the 1H in the number)
- Dielectric: X7R
- Tolerance: +/-10 % (the K in the number)
- Case: 1206, 3.2 x 1.6 mm, 0.65 mm maximum thickness
- Construction: multilayer ceramic, surface mount, two end terminations
Applications
- Replacing a 3900 pF 1206 chip on a board being repaired
- Bypass, coupling and general filtering on 1206 pads in prototypes and hobby builds
Frequently Asked Questions
What does 392 in the part number mean?
39 followed by two zeros: 3900 pF, which is 3.9 nF or 0.0039 uF.
Can this stand in for a C0G 3900 pF part in a timing or filter circuit?
Only where the circuit can live with some drift. C0G is the dielectric chosen when a timing interval or a filter corner has to hold still across temperature; X7R gives up that stability for more capacitance in a small body, and it suits bypass, coupling and general filtering.
X7R reads like a model number but works like a weather report: the X names the cold end of its rated span, the 7 the hot end, and the R how far the value may wander across that span. Match those three characters on the parts list before this chip goes on the pads.
