Frequently Asked Questions
What capacitance and voltage rating does PHE850EA4680MA04R17 provide for AC line filtering?
The PHE850EA4680MA04R17 provides 680nF capacitance rated at 100V AC with ±20% tolerance, making it suitable for X2 across-the-line EMI filtering in switching power supplies and motor control circuits connected to low-voltage AC mains.
What does the X2 safety rating of PHE850EA4680MA04R17 mean for power supply designers?
An X2 class rating per IEC 60384-14 allows the PHE850EA4680MA04R17 to be connected directly across AC power lines up to 275V AC (working voltage); if the capacitor fails, it does so safely without creating a fire or shock hazard, satisfying safety agency requirements in consumer and industrial power supplies.
How does the self-healing metallized film dielectric in PHE850EA4680MA04R17 improve reliability versus foil capacitors?
Metallized polyester film has a thin aluminum electrode that vaporizes locally around a dielectric breakdown spot, clearing the fault and restoring insulation within microseconds; this self-healing property means the 680nF capacitor can survive thousands of transient overvoltage events that would permanently short a foil-type capacitor, extending service life beyond 100,000 operating hours in typical AC line environments.
Which through-hole footprint does PHE850EA4680MA04R17 use, and how does it fit into standard PCB layouts?
The PHE850EA4680MA04R17 uses a radial through-hole package with 4mm lead pitch and 17mm lead length, fitting standard 0.2-inch or 5mm hole-grid PCB layouts commonly used in power supply input filter boards and motor run capacitor positions on 100V AC circuits.
