Selecting 200 kHz high-frequency and 965 kHz megasonic cleaning elements
High-frequency and megasonic projects often address finer surfaces and features, but they are not simple frequency substitutes and require different drive, mounting and process validation.
Two product directions
STC-4SH-25200K is rated at 200 ± 5 kHz, 30 W and Ø30 × 33 mm. P4-70.5×30.5×2.2 is rated at 965 ± 10 kHz, 10000 pF ± 10% and 0.3 Ω. Their structures and system requirements differ.
Information needed for project evaluation
Provide part material and dimensions, target particles or contamination, surface requirements, tank or flow-channel design, liquid medium, temperature, generator conditions and cycle target.
- Do not extrapolate megasonic results directly from low-frequency cleaning experience.
- Evaluate drive matching, mounting, thermal management and long-term stability.
- Validate the process with representative parts and contamination.

TECHNICAL FAQ
Common customer questions
Can a megasonic element be bonded directly to a standard cleaning tank?＋
The element specification alone is insufficient. The mounting substrate, drive and fluid system must be evaluated together.
Which cleans better, 200 kHz or 965 kHz?＋
There is no universal answer without the part and process. Select through contamination targets, surface requirements and sample testing.
