KeL-com Product Information
This page is intended as a supplement to the product entry for the KeL-com line of filter products. The tables below contain Product Notes and information on Part Numbering, PCB Layout and Reflow Profile.
KeL-com commercial filters offer enhanced design to manufacturing solutions. The product line is standardized through design and packaging to provide engineers with filters which are ideally suited for high-volume, quick-turnaround commercial/industrial applications, and is featured in Filter Wizard.
KeL-com standard filters achieve typical lumped element performance while utilizing commercial grade components and a manufacturing-friendly open frame, leadless surface mount package.

Installation Notes
 |
- When handling KeL-com products, avoid touching any solderable surface with bare hand or other contaminents as solderability may be reduced.
- KeL-com filters are made of very durable materials. However, mishandling of the product will damage the device. Avoid forcing the product into place by any means.
- KeL-com products can be cleaned via solvent based, aqueous, semi-aqueous, and alcohol based systems. Be sure to completely dry the units as any entrapped moisture will cause erroneous electrical performance.
- A typical reflow profile is provided above. The relative mass of all components should be considered when establishing a reflow procedure. Higher density board populations may take longer to achieve reflow temperatures.
- All KeL-com filters are assembled using SN96 high temperature solder. K&L recommends that customers use SN60 or SN63 or an equivalent during installation for signal and ground connections.
- The rate of heating and cooling must be controlled to preclude thermal cracking of the devices. Processes, heating or cooling, should not exceed a rate of 200°C per minute. Spikes must not exceed 100°C maximum for any solder operation. Avoid forced cooling or contact with heat sinks, such as conveyor belts, metal tables or cleaning solutions, before the units reach ambient temperatures.

Product Notes
|
Note 1 |
Center frequencies from 3 to 6 GHz are available by request. |
|
Note 2 |
Other filter types such as lowpass, highpass, and notch are available by request. |
|
Note 3 |
Bandwidths up to 100% are available by request. |
|
Note 4 |
Due to manufacturing variations, please observe these guidelines: |
 |
- Actual attenuation at any given frequency point may vary by +10%.
- Actual bandwidth may be wider than specified (typically 5 to 10%).
- Passband insertion loss may exceed given value (10% maximum).
