PHE844 Series, Class X1, 440/480 VAC, 105°C
Overview
Applications
The PHE844 Series is constructed of metallized
polypropylene film encapsulated with self-extinguishing
resin in a box of material meeting the requirements of UL 94
V–0.
For use as a electromagnetic interference (EMI) suppression
filter in across-the-line applications requiring X1 safety
classification. Suitable for use in situations where failure of
the capacitor would not lead to danger of electric shock.

The 100% screening factory test is carried out at 3,000 VDC. The voltage level is selected to meet the
requirements in applicable equipment standards. All electrical characteristics are checked after the test. It is
not permitted to repeat this test as there is a risk to damage the capacitor. KEMET is not liable in such case
for any failures.

Film Capacitors – Metallized Polypropylene Film EMI Suppression Capacitors
PHE844 Series, Class X1, 440/480 VAC, 105°C
Soldering Process
The implementation of the RoHS directive has resulted in the selection of SnAgCu (SAC) alloys or SnCu alloys as primary solder.
This has increased the liquidus temperature from that of 183ºC for SnPb eutectic alloy to 217 – 221ºC for the new alloys. As a
result, the heat stress to the components, even in wave soldering, has increased considerably due to higher pre-heat and wave
temperatures. Polypropylene capacitors are especially sensitive to heat (the melting point of polypropylene is 160 – 170ºC). Wave
soldering can be destructive, especially for mechanically small polypropylene capacitors (with lead spacing of 5 mm to 15 mm),
and great care has to be taken during soldering. The recommended solder profiles from KEMET should be used. Please consult
KEMET with any questions. In general, the wave soldering curve from IEC Publication 61760-1 Edition 2 serves as a solid guideline
for successful soldering. Please see Figure 1.
Reflow soldering is not recommended for through-hole film capacitors. Exposing capacitors to a soldering profile in excess of the
above the recommended limits may result to degradation or permanent damage to the capacitors.
Do not place the polypropylene capacitor through an adhesive curing oven to cure resin for surface mount components. Insert
through-hole parts after the curing of surface mount parts. Consult KEMET to discuss the actual temperature profile in the oven,
if through-hole components must pass through the adhesive curing process. A maximum two soldering cycles is recommended.
Please allow time for the capacitor surface temperature to return to a normal temperature before the second soldering cycle.

Selective Soldering Recommendations
Selective dip soldering is a variation of reflow soldering. In this method, the printed circuit board with through-hole
components to be soldered is preheated and transported over the solder bath as in normal flow soldering without touching
the solder. When the board is over the bath, it is stopped and pre-designed solder pots are lifted from the bath with molten
solder only at the places of the selected components, and pressed against the lower surface of the board to solder the
components.
The temperature profile for selective soldering is similar to the double wave flow soldering outlined in this document,
however, instead of two baths, there is only one bath with a time from 3 to 10 seconds. In selective soldering, the risk of
overheating is greater than in double wave flow soldering, and great care must be taken so that the parts are not overheated.
