LGF Filter – How it all started
Company
In 1994, the visionary minds of Dipl.-Ing. Lengenfelder and Dipl.-Ing. (TU) J. Geling embarked on a journey to revolutionize the development and distribution of line interference suppression filters. With decades of combined expertise in soft magnetic materials, inductive components, and interference suppression assemblies, they laid the foundation for an innovative venture. By 1995, we proudly delivered our first customer-specific network filters, marking the beginning of a legacy.
As our commitment to excellence grew, so did our company. By mid-1998, we found a new home at Regensburgerstraße 215, a dynamic space where research, development, manufacturing, distribution as well as product quality and process management converge seamlessly under one roof. This became the nucleus for our relentless pursuit of product perfection.
In 2011, our proven processes earned the prestigious DIN ISO 9001-2008 certification, a testament to our unwavering standards. Strategic expansions in 2015 transformed our facilities, providing enhanced storage and production capabilities. A pivotal moment came in 2016 when Dipl.-Ing. (TU) Florian Geling assumed ownership, steering us into a new era.
The recertification of our Quality Management System according to DIN EN ISO 9001-2015 took place in 2017, 2020 and 2023.
Today, LGF Filters Elektrotechnik GmbH & Co. KG stands not just as a manufacturer but as a beacon of creativity, ready to elevate your expectations in the electrical solutions field. Welcome to the innovation hub that is LGF Filter Elektrotechnik GmbH & Co. KG — where precision meets progress.

LGF Filter -What can you expect from us?
Responsible innovation –
we live our philosophy
“Competence that
speaks volumes”
A high level of education, active participation in EMC working groups and clusters in the field of power electronics as well as collaborations with scientific institutes and partnerships with industry leaders in energy, medical, and automation technology keep us at the forefront of technology.
“Flexibility is paramount”
Final assembly, a modular device structure, and the provision of pre-assembled standard modules enable a high flexibility degree. Our standard products are always available from stock. With our toroidal winding machines, we can efficiently manufacture a wide range of chokes, from small batches to large-scale production, saving both time and costs. By arrangement, we can also “buffer” manufacturing materials and products from our production partners, for example, in the Far East.
“100% Quality
is our standard”
At LGF Filter, 100% quality isn’t a goal; it’s our standard.
Our comprehensive quality assurance system, modern measurement and testing systems result in an exceptional fulfillment rate of over 99.8%.
“We don’t take ‘no’
for an answer”
“Can’t” is not in our vocabulary.
We thrive on challenges, turning them into opportunities.
Our vast experience, reliability, rapid response and adaptability allow us to deliver innovative, bespoke solutions at competitive prices.
