Note: Pulse withstanding capabilities are value dependent.
Value above the cutoff value, shown above, will meet all the surge test requirements shown on next page.
FEATURES
• Special Vishay Dale design provides lightning withstand
characteristics along with resistor functionality
• A thicker tin oxide power film system provides lightning
surge absorption capabilities
• Higher turns ratio and glass substrate provide sharper
fusing characteristic than the standard flameproof product
line
• Protect against a variety of electrical hazards which can
change or destroy sensitive electronic equipment including
high energy voltage surges caused by power line anomalies
(direct power crosses or inductively coupled effects) and
other momentary overvoltages

Lightning pulse wave forms are defined by three numbers:
•Maximum time to reach peak voltage level (typically 10 µ seconds).
•Minimum time for voltage to decrease to half value.
•The peak voltage level.
Three examples are shown below.
10 by 560 — 800 Volts FCC — Metallic Surge
10 by 1000 — 1000 Volts REA — Current Surge
10 by 160 — 1500 Volts FCC — Longitudinal Surge

These graphs show the relationship between resistance value and pulse withstanding voltage for FP1/2P thru FP3P using a
1.0% resistance shift after 10 pulses as the figure of merit. The stable operating region of each package is on the right side of
the appropriate line.
