Expanded Radial Fuse Family OffersMore Solutions for Space-LimitedApplications

300Vac SR-5H Series andSR-5 Fuses Down to 40mANow Available

• Extensive Offering

The new SR-5H Series and more SR-5 low-amp

ratings (now 40mA to 6.3A) expand an already diverseoffering of radial fuses that include fast-acting and time-delay versions. IEC and UL design options meet today’s various worldwide electronic design requirements.

• SR-5H High-Voltage Advantage

The SR-5H Series provides protection up to 300Vac with an interrupting rating of 100A - ideal for electronic lighting ballasts.

• High Amperage Certifications

These Cooper Bussmann radial fuses have IEC and/or UL certifications across the entire amp range, including the higher 5-10A ratings. The higher

wattage requirements of today’s end products means these higher amp-rated fuses are specified more and more.

• Space Savings

Round SR-5 radial fuses offer equivalent product performance to typical 5mm glass fuses with a 60% footprint reduction. The rectangular SS-5 fuses offer an additional 33% reduction to the SR-5 footprint.

• Cost Effective

Through hole mounted radial fuses do not require the added expense of axial leads, clips or a holder for PC board mounting. This results in a cost effective alternative to traditional electronic ferrule fuses.

Application Notes

Power supplies, power adapters and battery chargersplay a critical role in the operation of virtually all

consumer electronic devices. These power supplies orbattery chargers convert high AC voltage from the walloutlet to the low DC voltage used to operate today’sconsumer electronic products. These include note-book computers, printers, MP3 players, mobile

phones, high definition televisions, DVD players andset top boxes. Because these products are pluggedinto the wall, they require primary circuit protection, asthe device can be exposed to dangerous overcurrentevents.

The Cooper Bussmann SR-5, SS-5 and new SR-5HSeries of radial leaded fuses provide cost effective primary circuit protection without sacrificing

performance in space-constrained power supply

applications. The IEC designs have approvals through6.3A, and UL designs through 10A.
