Nihon Kohden Cardiolife TEC-7621C Defibrillator Capacitance HV
Capacitor NKC-4840SA 4.8KV 40μF
► Brief Introduction
The Nihon Kohden Cardiolife TEC-7621C Defibrillator Capacitance HV
Capacitor NKC-4840SA 4.8KV 40μF is a component used in
defibrillators manufactured by Nihon Kohden, a company that
specializes in medical equipment. Specifically, this component is a
high-voltage capacitor with a capacitance of 40 microfarads (40μF)
and a voltage rating of 4.8 kilovolts (4.8KV).
In a defibrillator, capacitors like the NKC-4840SA store electrical
energy, which is then discharged in a controlled manner to deliver
a therapeutic shock to a patient's heart in cases of cardiac arrest
or certain heart rhythm abnormalities. The high voltage allows for
the rapid delivery of a large amount of energy when needed.
The HV capacitor can store lethal amounts of energy. Be sure to
discharge this capacitor before touching any high voltage component
(HV capacitor, HV inductor, relay unit, paddle socket or paddles)
of the instrument.V
► Specification

| - Minimum 150 minutes continuous monitoring |
| - Minimum 90 minutes fixed mode pacing (180 pulse/min, 200 mA) |
| With the fully charged new battery at 0°C, the defibrillator can
perform: | - Minimum 50 discharges at 360 J |
► Removing the HV Capacitor and Relay Unit
1. Remove the battery pack, memory card and lower casing.
2 Remove the AC/DC unit. Refer to “Removing the AC/DC Unit”.
3. Remove the main chassis and main board. Refer to“Removing the
Main Board”.
4. Make short-circuit the two HV capacitor terminals with the short
bar which is connected to the ground terminal on the wall with the
ground lead.
5. Remove the four M3 pan screws with spring washers which secure
the HV capacitor to the lower casing and remove the two HV
capacitor fixing brackets.
6. Remove the cap of the CNP552 and CNP553 wires from the HV
capacitor.
7. Remove the HV capacitor.
8. Remove the three wires (CNP555, CNP554 and CNP556 wire) which
connect the HV inductor and relay unit from the HV inductor.
9. Pull out the relay unit.
After replacing the HV capacitor or relay unit, always check the
following:
• TTR value
• Delivered energy
• Charge time
