Key Features
- 0.1 µF capacitance at 100 V DC rating with tight ±5% tolerance for precise timing and filter applications
- Metallized polyester (Mylar) film dielectric delivers low dissipation factor (DF < 0.4% at 1 kHz) for energy-efficient AC coupling
- 5 mm lead spacing (LS 5 mm) fits standard through-hole PCB grids, simplifying board layout and component sourcing
- Self-healing metallized film construction recovers from minor dielectric breakdown events, extending operational service life in high-voltage snubber circuits
Applications
The MMK5104J100J01L16.5TA18 is commonly used in audio amplifier coupling and decoupling stages where its stable 0.1 µF capacitance and 100 V rating prevent DC bias from reaching downstream circuits. It is also effective in RC timing networks and EMI filter designs operating up to 100 kHz, benefiting from the low dissipation factor of the polyester film dielectric. Power supply snubber circuits use this part to suppress switching transients, leveraging the self-healing metallized film construction for long-term reliability.

Frequently Asked Questions
What is the voltage rating and capacitance value of the MMK5104J100J01L16.5TA18?
The MMK5104J100J01L16.5TA18 is rated at 100 V DC with a capacitance of 0.1 µF and a tolerance of ±5%. This combination is suitable for audio coupling stages, RC timing networks, and low-voltage power supply filter circuits where precise, stable capacitance within a ±5% window is required for predictable circuit performance.
What dielectric material does the MMK5104J100J01L16.5TA18 use and how does it affect performance?
The MMK5104J100J01L16.5TA18 uses a metallized polyester (Mylar) film dielectric, which provides a dissipation factor below 0.4% at 1 kHz and good capacitance stability across temperatures from -55°C to +85°C. Polyester film dielectrics exhibit higher capacitance density than polypropylene at a lower cost, making this part a practical choice for general-purpose decoupling and filtering up to approximately 100 kHz.
What is the lead spacing of MMK5104J100J01L16.5TA18 and why does it matter for PCB layout?
The MMK5104J100J01L16.5TA18 has a 5 mm lead spacing (pitch), which matches the standard 5 mm through-hole PCB grid used by most DIP and leaded component designs. This 5 mm pitch eliminates the need for custom pad layouts and ensures compatibility with universal prototype boards and automated through-hole insertion equipment, reducing design and assembly time for high-volume production.
How does the self-healing metallized construction of MMK5104J100J01L16.5TA18 extend service life in snubber circuits?
In metallized film capacitors like the MMK5104J100J01L16.5TA18, if a localized dielectric breakdown occurs at a weak spot, the vaporization of the thin metal electrode around the fault isolates it and restores insulation resistance within microseconds. This self-healing property allows the capacitor to withstand brief voltage spikes above the 100 V rating without catastrophic failure, which is why snubber circuits across relay contacts and MOSFET drains often rely on metallized film capacitors rated for continuous service up to 10,000 hours.
