Product Overview
Shenzhen Surong Capacitors 2A472K - polyester film (PET/Mylar) capacitor, 4.7nF (0.0047µF / 4700pF) at 100V DC with ±10% tolerance. Through-hole, radial-leaded construction. Reddish-brown epoxy body is the standard finish for this capacitor type. A reliable general-purpose film cap suited to filtering, coupling, DC blocking, and timing work.

Frequently Asked Questions
Is this capacitor polarized?
No. Polyester film capacitors are non-polarized and can be installed in either orientation.
Can this be used in an AC circuit?
Film capacitors are not polarized and can pass AC signals. However, the 100V rating is a DC rating. In AC applications, keep the peak AC voltage well below 100V to avoid overvoltage stress. For sustained AC use at voltages approaching the rating, a capacitor with an explicit AC voltage rating is the safer choice.
What is the lead pitch?
Not confirmed - verify against datasheet before use. Leads measure approximately 35mm long in photos and appear standard for this body size, but exact pitch should be confirmed before committing a PCB layout.
Is a datasheet included?
Not included.
A film cap this small rarely gets a second look - it just quietly does its job, keeping signals clean and timing honest. Drop it in wherever your schematic calls for a 4.7nF Mylar and move on.
