A pack of ten 100nF ("104" - 100000 pF) Through Hole Ceramic Capacitors.
I have personallyverified that these are 100nF +/- about 20% (on my typical multimeter, nothing fancy).
Supplier specified them as 50v, other than that no more specifications available.
All of our products are shipped from Christchurch, New Zealand using CourierPost for NZ, and Airmail for international.
